Do aliens use hairspray?

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Life - A new study indicates that Mars formed from similar building blocks to those of Earth, but that there were differences in how the two planets evolved. See article.
g Intelligence - Chemicals such as those found in hairspray might one day serve as signs that aliens have reshaped distant worlds, researchers say. See article.
g Message - To contact an alien civilization, humanity might want to consider a Bracewell probe — a hypothetical concept for an autonomous interstellar space probe dispatched for the express purpose of communication with (an) alien civilization(s). It was proposed by Ronald N. Bracewell in a 1960 paper, as an alternative to interstellar radio communication between widely separated civilizations. See article.
